CODE-BOOK.

To all whom t may concern.'

Be it known that 1, GEORGE BoNNnLL, a citizen ofthe United States, residing at Ghicago, inthe county of Cook and Stateiof illinois, have invented certain newv and'useful Improvements in Code-Books, of which the following is a specification.

This invention relates to a code book for use in the transmission ofnumbers by telegraph and it is especially adapted for the use of railroads and other industriesin referring to the numbers of cars and the like.

vThe principal object of the invention is to provide an improved code book having an improved arrangement of ycode words and numbers therein for securin efficiency and economy in the use of the te egraph or any other form of communication. The invention is adapted to overcome the necessity of transmitting car numbers,` for example, by the use of a separate word for each figure of the number, and an important feature of the invention is` the use and arrangement of words which permit vthe numbers to be codified readily `and insure a correspondingly rapid translation of the codified number.

`The .improved'code book comprises a series of numbers ranging from 1 to 999, and these numbers are arranged in columns in numerical order so that any number of one or two or three figures can be located in its proper place in the book. The code words used for vtransmitting these numbers are ordinary and usual words such as are found in the dictionary, and these words are selected and arranged in alphabetical order, the words progressing alphabetically with the numerical progression of the numbers so that any word can be readily located in the code book by vreason of this alphabetical arrangement.

The alphabetical arrangement of the words extends through several letters of the words so that a large number of the words beginning with a single letter of the alphabet can be used for designating a corresponding series of numbers.

A. person desiring to transmit any number of six figures, for example, examines the code book and selects the words which correspond to the figures or groups of figures which make up the number. Thus in codig fying a six figure number it is desirable to select words corresponding to two groups of three figures each so that the number can be transmitted by means of two words. In

translating the codiied number, the operator merely refers to the parallel columns in the code book.

All of the numbers from 1 to 999 and lcorresponding code words are arranged in parallel columns of Section One of the code book. The book also comprises Section Two which contains a series of code words for transmitting corresponding numbers which consist partially or wholly of ciphers. This section of the book will be referred to for transmitting numbers 0r parts of numbers including ciphers, and also for transmitting numbers in which ciphers precede or follow other numbers of the figure. This section of thebook also includes a number ofadditional code words which can be used for transmitting any other desired information. Section Three of the code book consists of a list of code words and a parallel arrangement of corresponding fractional `numbers which are arranged in numerical order. The three sections of the book and the numbers and -figures embodied therein arearranged as shown in the accompanying drawings: Y i In the accompanying drawings va small extract from each section of the book is illus- `trated, the dotted lines between successive words and numbers in the columns being Vused to indicate that certain numbers and mitted by telegraphing the code word as follows: Awake Fair. Tn a similar manner the number 2894188 can be codified and transmitted by using the words Betide Careem7 the number 346000 will be represented by the words Blush Flay, and the number 1321091 will be represented by the words Aback Blast Giddy. Tt will be observed that the word Flay representing three ciphers has been selected from Section Two of the book and also the word Giddy which represents the gures 091. All of the other words in the examplesfjust mentioned have been selected from Section One of the code book. Any number-canthus be codified, including fractional numbers lwithout the4 necessity of paying any attentionto decimal points. y Whentransmittmg a series of separate numbers 1n a continuous list, where no word or other character intervenes between separatenumbera the word And is used to separate the numbers, thus: p

ibook. For example, 10001: Able Floor.

Where prefix` letters are a part of any number these'should be stated, as they are, in vconnection vwith the reference word quoted for the number.

The code book therefore permits the ready codification and the ready translation of the code words due to the novel selection and arrangement of theseY words and numbers in the code book. A distinguishing feature of the invention is the novel arrangement of the numbers "and the words in numerical and alphabetical order, respectively, whereby a person having a number can readily locate the word or words to be used in codifying it and a person receiving the code words can quickly find the corresponding numbers without reference to a key or anything eX- cept. the code book. The words used are short and are `complete words so that they are much more readily understood and trans- Y mitted by vthe telegraph operator thanv any other system of code words heretofore known. l

Although I have shown and described one embodiment of the invention for purposes vof illustration, it will be understood that it may be employed in various other ways lwithout departing from the scope ofthe appended claims.
